SmartLog/Logs vs Tracker/fw.log in R8010

R80.10 Logs view (SmartLog) doesn't seem to find identical results from my dataset as the fw.log view (Tracker) does. My filter in both is something like 10.10.0.0/16 and they seem to find different hosts with that, with the same time limit. Logs view finds only one host and fw.log finds several as expected. Has anybody else run into this?
